Desc: Voyage to the American Stonehenge: With Alexei Vranich. Great monuments were built in the ancient city of Tiwanaku on the shores of Lake Titicaca in Bolivia. The origin of these monuments has given rise to a small economy based on exaggerated claims as to who were the creators of this city. Now, archeologists struggle to understand how these stones were moved and carved by the people that would have actually lived there. A team gathers to build a boat in the traditional way and move a stone identical to the ones found in Tiwanaku. The only rule is that they may not use modern tools, just their best understanding of ancient tools and techniques. Gain a first-hand experience, standing side by side and talking with the researchers undertaking this amazing mission.
